microscopy is a non-destructive technique which uses visible light passed
through a series of lenses to produce enlarged sample images. It is also known
as light microscopy. Virtually any
sample can be analyzed using OM with the only requirement being that can be
placed under the microscope’s objective lens.
. The degree of magnification available is widely variant, typically up
to 100x, and can be easily changed by altering the magnification power of the
objective lens. This technique can be used to examine the homogeneity,
morphology, topography, color, and other physical characteristics of a sample. Some microscopes can be coupled to cameras
for image preservation. Microscopes are typically employed as benchtop instruments, but some
smaller handheld microscopes are also commercially available. It is an extremely mature analytical
technique and instruments are widely available from a large number of
manufacturers. Microscope prices vary
widely depending on the quality and complexity of the lens optics.
